Correct Answer

(C) Continuous chips with built-up edge are formed

[#252] In oblique cutting system, the cutting edge of the tool
Correct Answer

(C) May not clear the width of the workpiece

Explanation

Solution: In Oblique cutting, cutting edge travels, making an angle with the normal of cutting edge.

[#254] Which of the following operation is first performed?
Correct Answer

(D) Drilling

[#255] The material which on machining produces chips with built up edge is
Correct Answer

(D) Ductile material

Explanation

Solution: Ductile material Produces Chips with built up edge. Built up edge (BUE) is an accumulation of material against the rake face, that seizes to the tool tip, separating it from the chip.
